There's something about the idea of writing, and thinking about writing as a form of prayer - the way as a writer you call out into the world and throw your words into the world. You're not praying to a god, but you're almost conjuring a reader to arrive. That's what books do: they're an invitation to readers.
When I write fiction, I have the illusion of being able to control these fictional worlds and these characters, and to make them say what I want them to say. Of course, the problem is that it is an illusion, and by the end of it you realize that you're not in control of it at all; the characters have taken over, and they're driving the vehicle.
